Oh gosh, Nonny, the way you worded your ask made me burst into giggles. xD
Some people prefer to use the k as a distinction between stage magic/sought of hand and witchcraft magic. Neither is wrong, though you’ll have many express why one or the other is wrong or just makes you sound conceited and/or arrogant and/or ignorant if you use it.
Do whatever you want and ignore the haters. :3
Ok, now that I’m not falling asleep…
The K-spelling was created by (I believe) Crowley, because it fit nicer with [thing to do with numbers] than the C-spelling.
I don’t actually remember who or what, so I’m going to pass this off to Sec, because I know she knows, and her page is where I heard about it.

It’s not just a special k (which people like to throw in there as a pejorative slang) there is actually a purpose or a reason why its spelled this way. It also has to do with the will and separating the Divine Will from the performance of fake magic (because anyone who doesn’t use the Divine Will [read: witchcraft, folk magic, etc] are fakes – not just stage magic – but literally calling witchcraft and folk magic and any other forms that do not incorporate this Divine Will as fraudulent and bullshit).
So. Yeah……
Thanks, Sec! xD
Also, the god of knowledge, Google, returns much different search results between magic and magick.
